Default Help, Right Front brake sticking...

The right front tire brake is not releasing all the way when driving. The rim is much hotter than the left side when I felt it parked.
I have replaced the caliper and pads already, bleed the fluid with new. All other tire roll free when on the lift, Right front sticks. HELP

Is there a check valve in the ABS that could be stuck?

1988 Vert has the problem

seems like are the bolts on which the calipers are attached to.. i cleaned these bolts with brake cleaner then lubricated with dry graphite.

I suspect the brake hose.If you unbolt the brake,hose does the fluid Pee out or dribbles?If it dribbles and leaks drop then the hose is bad.It should flow out fast with a good hose.I had the same problem with a GM Van and one of the wheels stuck,got damn hot and I replace the caliper,brakes,rotors and etc.It still did the same thing.When I unbolted the hose I noticed it dribbled out.A new hose fixed the problem!
Give it a shot.

Last fall I noticed my RF brake pads were wearing more than the left so I replaced the front brarkes, including the hoses, and completely flushed the brake system by bleeding weach wheel till clean fluid came out. The the problem is solved.

Also check the mounting bracket that it has not become distorted over time.

When I replaced the caliper, I checked the hose, it seemed to run free. Fluid came through pretty well as I circulated the brake fluid through it. Any additional thoughts?

Taking a guess online is tough.Since the brake hoses arent very expensive,I suggest you replace it and see if the problem is still there.If it is,youre not gonna be out much money and youll have a better chance to narrow it down from there,if the problem still persists.

My 88 GTA had the same issue. It was the rubber brake line. The line had decayed inside and had some loose rubber flapping around. It would not release the pressue at the same rate the other side did and if I was in heavy stop and go, the bad side would grab sooner than the other, pulling hard in that dirrection untill the other side caught up.

It sure sounds like it is the flexible brake line.

Very easy and cheap to fix. Having your hub catch on fire due to heat build-up is very expensive.

Doesn't matter, replace them both. They can sometimes act like a one-way valve when they get old, not letting the brake fully release. I recommend always changing hoses and calipers together.
